Seena (senna) leaves, known for their natural laxative properties, are harvested, dried, and processed for use in herbal medicines. India, particularly Rajasthan, Gujarat, Haryana, and Madhya Pradesh, is the world’s largest producer of senna leaves, growing them mainly in dry, semi-arid regions. The harvest season runs from January to April.
India dominates the global senna export market, supplying most of the world’s demand. Key export destinations include Europe, the Middle East, North America, and Asia, where Indian senna is valued for its quality and consistency.
